To automate or not to automate - that is the question

void do_i_automate()

{

    if ((Time spent testing)*10) < (time spent automating and maintaining the automated tests) {

        DON’T AUTOMATE IT;

    }

else

{

        AUTOMATE IT;

    }

(If you will test it more than 10 times the coming year and the total time spent testing it these 10 times exceeds the time automating and maintaining the automated tests, automate it)
